G. H. GREGORY. GAS GOVERNOR,

UNITED STATESA PATENT @Erica GEORGE n. GREGORY, OE BROOKLYN, AssieNoE 'ro CHARLES STANFORD urron, or NEW YORK, N. Y.

GAS-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 414,525, dated November 5, 1889.

Application led March l1, 1889.

To all? whom it may concern:

Be it known that I, GEORGE II. GREGORY, a citizen of the United States, residing at Brooklyn, county of Kings, and State Ot New York, have invented a new and useful Improvement in Gas-Governors, of which the Vfollowing is a specification.

My invention relates to a self-acting cheek or regulator in a gas pipe or passage, such as to permit substantially unrestricted iiow of gas at normal or less than normal pressure, but suoli as from any increase of pressure to more or less consti-ict or close the passage, and that in proportion to such increase.

My improved governor is capable of application at any portion of a gas-pipe, either at the meter or immediately adjacent to the tip.

In the accompanying drawings, Figure 1 shows the inventioirin vertical section. In this view a supplemental check is shown. Fig. 2 is a similar view without the supplemental check, showing the adaptablility of the burner to different forms of tip. Fig. 3 is a plan of the disk.

The governor consists of two parts 1 2 which at their adjacent ends are expanded and hollowed so as to embrace a chamber 3. Flanges i on the expanded portions screw together, as indicated, and form the side of said chamber 3. The upper surface of part 2 is a broad tlat bearing or Hoor 2', forming the lower valve or seat of a disk 5 of mica or other similar light material. The small gas-supply open-v opening, so that the greater the pressure of the incoming gas the more closely will the mica disk hug its seat and the smaller will be the opening provided for the gas. This is the action even without any upper member for the gas-governor;4 but it is aided by forming the ceiling of chamber 3 with the recess 8 and downwardly-projecting neck 9, so that the iVings 7 on the disk 5 or otherv Serial No. 302,885. (No model.)

said ceiling, together with the sides of the chamber, act to direct down upon the top of the disk the gas which passes upward around its edges. The lower edge of this neck is provided with a number ot' notches 10, so that a constant Opening for the gas will be provided, even though the mica disk should be thrown. up against said neck, which thus forms its upper valve-seat. Such movement of the disk, however, is abnormal, occurring only in a case of shock given to the instrument. The size of the Opening G in the lower valve-seat is varied according to the pressure or quality of the For burning gasolinegas it is made of such diameter as to hold the mica disk constantly against its upper seat, and the depth or size of the notches 10 is regulated according to the number ot feet per hour to beburned. The upper memberl has a nipple 1l, bot-h interiorly and exteriorly screw-threaded. may receive a burner-tip directly, or a tip-1e ceiver maybe screwed over the nipple; or an auxiliary check 12 of the represented tubular form, and having an exterior -thread 12 and a longitudinal slit l2, may screw into the nipple, and the tip receiver may be screwed around it.

The auxiliary cheek 12 in the described association with the automatic regulator beneath it enables discretionary limitation of the automatic delivery. VvYhen the auxiliary check is added, the burner 13 is screwed on the outside of nipple l1, as shown in Fig. l.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s#

1. A gas-governor formed in two parts having a chamber between, one part having a dat broad valve-seat with a central supply-opening and the upper part having a downwardlyprojecting neck notched as described, for the purposes set forth.

A gas-governor formed in two parts having a chamber between them, said chamber having a flat floor or valve-seat, a vertical or substantially vertical side, and a recessed ceilin, the neck notched, as described, pro,

D jecting downwardly from said ceiling, and the flat light disk occupying said chamber, substantially as set forth.

The interior screw-thread" 3. In agasgovernoi, the combination of the part 1, expanded at its lowerl end and having flange 4, recessed ceiling, and notched neck 9,

and the part 2, having small supply-opening 6, the broad flat valve-seat surrounding said opening, and the disk 5, resting thereon and surrounded by flange 4, screwed into the flange of the upper part l, substantially as set forth.

4. In a gas-gove1no1, the combination of the following elements, to Wit: the service-pipe 2, having the broad floor 2', With small central orifice 6, the loose disk 5, seated thereupon, the part 1, screwed to said pipe 2 and having` the notched and downwardly-projecting neck 9 in the chamber 3, and having the upwardlyprojecting interiorly-thieaded nipple l1 and the optionally-adjustable check l2, as and for the purposes set forth.
